Abstract (en)
A process for producing a polymer of vinylic compounds comprising polymerizing at least one vinylic compound by using an initiator system comprising a compound containing, in the molecule, at least one group represented by the general formula: -C(-R<1>)(R<2>)-X where each of R<1> and R<2> represents an alkyl, aryl or aralkyl group, and X represents an acyloxyl, alkoxyl or hydroxyl group or a halogen atom, and a Lewis acid, wherein (1) at least one of pyridine derivative (A) selected from the group consisting of a pyridine derivative (A-1) substituted at 2-position and 6-position with methyl group respectively and a pyridine derivative (A-2) substituted at 2-position with an alkyl group of 2 to 6 carbon atoms and not substituted at 6-position, and (2) an organic Lewis base (B) other than said pyridine derivative (A> are present together in the polymerizing reaction system.
